After which, all of your active tabs will be immediately hidden from your browser window. The only tab that you’ll see is the tab that you’re currently viewing. The rest will be hidden.

Instead of clicking the “Expand All” option, just click on a specific page or tab that you wish to restore. This option is great especially if you don’t want others to see the rest of the tabs that you’ve previously hidden.
